so you need more than just the kit when using the kit?

no if you already have factory adjustable gears. but i'm not 100% sure if the DP Ergal gears would fit on the the 01+ 900s since the gear holder/flange has a different part number. the holders i'm using are from a 1100/1000/696/st3.

yes you'll need more than just the gear kit if you have the fixed steel ones.

it's going to be a little bit before an update. i finally tracked down some ie cams for cheap. thanks to "fastfrank racing" again. i don't want to pull the cams gears twice.

cool stuff

i bought new cam nuts and the larger diameter layshaft washer that goes between the 2 pulleys.

elastic nut part# 70350062A
(2) layshaft washer part# 85610622A . the new washers aren't as thick as the older 900 ones, so i doubled up


the 1000DS cam holders fit the 900 cams and layshaft. the diameter of the DP Ergal pulleys are just a few millimeters bigger in diameter than 900 ones.


here' the 1000DS holders on 900ie cams

told ya i'd be a little bit.

made new backing plates for the cam pulleys and finally bought the required belts.

the end of the tunnel is close.  [moto]

by backing plate, are you describing the giant washer?

and by diameter of the pulleys, I believe only the tooth count matters. the 18T is correct for the M900 and really old ass ones had the "square" pulley teeth, which you'd want to change to the round profile ones, like all the current production belts are designed for.

i'm sorry i meant the inner timing belt covers. i made some tiny ones out of aluminum.

also the new pulleys timing mark are in a different location. that's kinda why i made new inner timing pieces so i can mark where the new location is.

also the 20 tooth pulleys won't fit in the 18 tooth housing. i wasn't going to use them anyway.

i'll take some pics to show how i got everything to work. was a little more work than just throwing them on. what would be the fun in that?

I know how that goes.

On that project M900 motor/bike - I'm going to use the set of lightweight adjustable VeeTwo cam pulleys I had been saving for the 2vSBK since the 1100 motor will be able to get its own kit at that point I figure. What I learned was the "W" heads did not come with adjustable pulleys at all (and I happened to have a set of 18T lightweight non-adjustable pulleys in case for some reason I did not end up using the VeeTwo pulleys), but the V-heads off the 02 900SSie motor which are going on the bike DID come with the factory adjustable pulleys. Only issue is they weigh more than the VeeTwo's, so unless I find a reason not to use the VeeTwo's, I may have a spare set of factory adj. pulleys available.

What I really wanted, also, was for the layshaft pulleys to also be lightweight on my bikes - but the VeeTwo kits were only the ones for the cams - just a 2-pulley kit - even the 4v kits only came with 4 pulleys.   So I thought I was either out of luck, or would have to order a complete DP or STM (if those are even available still) lightweight adjustable pulley kit - giving me extra cam pulleys.

I originally thought the pulleys were the same as the non-adjustable pulleys in shape/design - and that's why I originally scored some of the lightweight non-adjustable 18T pulleys on the cheap. Wrong. Those 'plates' are affixed to the rollers themselves, and I would wager are fairly important in keeping the belt from walking off the pulley. (The middle "guide" is just like the big ass washer under the pulley on the cams).

Turns out, through some internet sleuthery (here (http://hunterdog.org.au/DiscussionBoard/index.php?topic=599.0)), the DP individual part number for the lightweight "driving" pulleys (the ones on the layshaft) could still be ordered through Ducati - though not inexpensively. So you could order two of part number 96437103B. (pulled the part number from the boxes in the pictures) - about $90 a pop iirc. They look like the bottom left pulleys in the next two pictures:

So that's what I've learned that may contribute to the conversation. Don't know if the other part numbers in those pictures are available to order individually, but that's knowledge dropping I can throw in here.

those are the pullies that the owner of commoto has and i thought he swapped to the larger 20 tooth belts.


it's going to be a little bit before i get some pics up. i having nightmarish problems with the valvetrain. for some reason the rockers are binding in the middle of opening the valve and won't complete a 360˚ rotation.  [thumbsdown] i'm not a very happy and patient person right now.

you gotta take a deep breath and walk out of the garage! I know how it feels though. A good break from work on the bike and a cleared head will make things easier.

Never had those plates on my M900 & took them off my 907 rear cyl 3 years ago.
Seems to work fine. I am careful w tension & centering of the belts, though.

The ones on the layshaft that are kind of like flanges?  and no troubles? I figure since they are like that on all the OEM layshafts that I have seen, that they were important.

My monster has no flange on the cam pulley.

The ones on the layshaft will keep the belts from walking off.

That's the ones I'm talking about that are flanged.

The pulleys at the heads have the washer behind them, between the spacer/bearings, but that's been all I've seen.

Some bikes had the outer edge of the cam pulley with a sheet metal type flange also. You could peel it off really easily.

I think that's what GM was referring to removing.

You read me like an open book, dp. ;)

oh, i had no idea the cam pulleys sometimes also had the flange - I've got a whole box of 18T cam pulleys - oem fixed, lightweight fixed, oem adj., and lightweight adj (DP and VeeTwo - and have played with a set of STM which I wish I had bought) - hadn't seen the flange on those, only on the layshaft pulleys or "driving rollers" as Ducati refers to them.

i feel all educated and stuff.  and i like it.

here's the differences in the 18 and 20 tooth cam pulley timing marks.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05973.jpg)

the 20 tooth layshaft pulleys are still marked the same as the 18's.
the 20 tooth DP layshaft pulleys have a different backspacing than the 18 tooth steel ones.


also the layshaft washers are different thicknesses.

here's the 900 layshaft washer
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05977.jpg)

and here's the 1000ds layshaft washer
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05978.jpg)

to solve that problem i just doubled up on the 1000ds washers. easiest way.

now tackling the layshaft pulley spacing differences.
i measured what i call the backspacing from the flanges size to the inside surface. here's how i measured.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05985.jpg)

the 900 steel pulley is 7.28mm
DP 1000ds pulley is 9.95mm

to compensate for the roughly 2.67mm thickness difference i used 2 of the 900 cam pulley washers that are a hair over 2.0mm thick.

before and after how i reshaped the 900 cam washer
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05980.jpg)


now to the pulley widths are differences. picture shows how i measured them.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC05986.jpg)

900 steel is 20.40mm
1000ds DP pulley 20.85mm

so with my caveman math, i think i'm in the clear.

here's how the pulley washer configuration goes.

ENGINE-reshaped 900 washer-DP pulley-2 1000ds washers-DP pulley-reshaped 900 washer-castle nut washer-castle nut

i'm sorry, but i tried compiling all this information in a neat fashion.

here's my not so fancy timing belt inner timing belt covers.

they peek over the timing belt just a little.

Hello

I'm looking to upgrade my fixed pulleys to ergal adjustable that I will anodize; however I'm not exactly clear about a couple things:

18t is what my 96 have; what advantage to going to 20t is there? DL, is it because those are the parts that were available to you?

If I stick with 18, am I correct if I believe that what I'll need is this kit:

http://www.speedsupplies.com/accessorylistingdetailpurch.asp?item=23610 (http://www.speedsupplies.com/accessorylistingdetailpurch.asp?item=23610) (18t version)

What flanges and washers would I need to complete the job? will part 16011051A  referenced in the OP work with both the 18t and 20t pulleys?

Called Ducati Seattle, Ducati Omaha, and Commoto today and none of the parts guys had a clue...

Thanks

Seems to me I'll need te 18t kit:

96436503B

Combined with2 flanges:

16010761A

Along with the special washers and torx screws...I just want to be sure I'm not missing anything...

The advantage with going to 20t is then you'll get to buy DS1000 belts and struggle to get them on and off the layshaft pulley.

18t will keep life simple.

Dunno about that 'kit' you linked, it's not very clear what all you're getting.

I suspect it's just aluminum pulleys that fit the adjustable OEM hubs on the heads.
So unless you already have a set of those, you'll need to buy those too.

I just used the 20 tooth setup since a new set of DP ones came up for sale cheap. At the time I couldn't find any fuel injected adjustable pulleys, DP 18 tooth pulleys or the STM ones. I made due with what I had.

Anyone know which bikes came from the factory with 18t adjustable cam pulleys, or where to source the "hubs" I would need?

You can buy a set of hubs and screw plates brand new for ~$100.

A cursory check of parts catalogues showed that ~'01 and after have adjustable pulleys.

I guess I didn't know what I was looking for...Ducati Omaha is even more clueless than me, they're acting like I'm asking them to decode the Bakshali Manuscript.

The "hubs" you're referring to aren't the flanges I've already referenced? I must be blind because I don't see anything else in the diagram besides those and the screw plates/washers.

Items #14 and #17.

You may be able to use your items #4, not sure what all you've got.

Yeah, my brother's 2001 M900Sie has them. One less thing to buy for him.
If you could find some.

What about getting someone to adjust the timing with oem steel pulleys offset wd keys?

I want the bling. :)

Thanks Speeddog, I was already accounting for those. But you were calling them hubs and I was calling them flanges.

Vee Two now operates from home on Ebay. He might have some. I got my Vee Two pulleys from Brad. I don't know if he has any left.

i have some of the madasl ones in stock.  they work fine.

i don't think brook is making them at the moment.  you'd have to ask him.

Madasl ones ???

I'm interested Brad.

Ah I just checked em out on your Bike Boy site.

I'm going to try to revive this thread to see if anyone can guide me here.  I have a '95 M900 Engine with fixed pulleys.  I bought a set of adjustable from Desmo-Racing ( http://www.desmo-racing.com/en/ergal-split-belt-roller-timing-kit-ducati-06-xml-245_457-1621.html ).  My tech is attempting to install and we are running into an issue. When the pulleys are seated there is not enough thread left on the shaft to secure the nut.  Does anyone have information on what we need to do at this point?  Did I miss something in this thread that contains the secret!?  Many thanks to any guidance.

Looks like it's still got the thin backing plate from the stock pulley on there.

Doesn't seem to need those.

I agree.

Does the centre sleeve protrude about 5mm too much? If it was flush then it would allow the nut to clamp both it and the pulley face.

So should all the torque seat on the centre sleeve and it therefore be proud of the pulley face by a mm or 2, or should it be flush or recessed a little? I guess aftermarket being alloy pulleys probably means the torque should go into the steel sleeve? I may look at some M900 heads to see how the oem is set up.

His pulleys have a counterbore on the back side of the center hub, lookes ~2mm deep.
That, plus the OEM flat plate (that's not needed with these pulleys) ~1mm thick.
So then the snout of the hub would be ~3mm further out than it should be.
And that's about what it looks like in his pic.

Here's the back side:

(http://www.desmo-racing.com/images/Image/KPA006D_8_1351363580.JPG)

Nut is supposed to pinch the hub up against the spacer that goes through the seal and up against the bearing on the cam.

Not supposed to pinch the pulley or the little front plate.

 [thumbsup]

Looks like that counterbore should be deeper and particularly if you want to run the guide plates.
Have you contacted the vendor?
